Difference between EBMM JP13 bridge vs. Floyd Rose Bridge (Setup)

I am not very handy when it comes to changing strings on floating bridges and usually get the guitar shop in town to set up my guitars that have floating trems. A friend of mine who is familiar with Floyd Rose trems offered to set up my guitar a full step down but I am wondering if there is anything he needs to know about the jp13 bridge compared to a Floyd Rose.

Thanks in advance.
